MAX9030/MAX9031/ MAX9032/MAX9034 Low-Cost, Ultra-Small, Single/Dual/Quad Single-Supply Comparators General Description The MAX9030/MAX9031/MAX9032/MAX9034 single/ dual/quad comparators are optimized for single-supply applications from +2.5V to +5.5V but can also be operated from dual supplies. These comparators have a 188ns propagation delay and consume 35A of supply current per comparator over the -40C to +125C operating temperature range. The combination of low-power, singlesupply operation down to +2.5V, and ultra-small footprint makes these devices ideal for portable applications. The MAX9030 is a low-cost single comparator with shutdown. The MAX9031, MAX9032, and MAX9034 are lowcost single, dual, and quad comparators without shutdown, respectively. The comparators' 4mV of built-in hysteresis provides noise immunity and prevents oscillations even with a slow-moving input signal. The input common-mode range extends from the negative supply to within 1.1V of the positive supply. The design of the comparator output stage substantially reduces switching current during output transitions, virtually eliminating power-supply glitches. The MAX9030 single comparator with shutdown is available in the space-saving 6-pin SC70 and SOT23 packages. The MAX9031 single comparator is available in tiny 5-pin SC70 and SOT23 packages. The MAX9032 dual comparator is available in 8-pin SOT23 and MAX(R) packages, and the MAX9034 quad comparator is available in a 14-pin TSSOP package.

They have an operating supply voltage from +2.5V to +5.5V when operating from a single supply and from 1.25V to 2.75V when operating from dual power supplies, and consume only 35A. Their common-mode input voltage range extends from the negative supply to within 1.1V of the positive supply. Internal hysteresis ensures clean output switching, even with slow-moving input signals. Shutdown Mode The MAX9030 comparator comes with a power-saving shutdown mode. When in shutdown, the supply current drops from a typical 35A to 0.05A, and the outputs become high impedance. SHDN has a high input impedance and typically draws 0.1A when connected to VSS or VDD. A maximum logic low voltage of 0.3V x VDD applied www.maximintegrated.com Comparator D Inverting Input Comparator D Output to SHDN places the device in the shutdown mode. A minimum logic high voltage of 0.7V x VDD applied to SHDN will enable normal operation. To disable shutdown, connect SHDN to VDD. Applications Information Adding Hysteresis Hysteresis extends the comparator's noise margin by increasing the upper threshold and decreasing the lower threshold. A voltage-divider from the output of the comparator sets the trip voltage. Therefore, the trip voltage is related to the output voltage. These comparators have 4mV internal hysteresis. Additional hysteresis can be generated with two resistors using positive feedback (Figure 1). Use the following procedure to calculate resistor values: Maxim Integrated 6 MAX9030/MAX9031/ MAX9032/MAX9034 R1 VREF R2 Low-Cost, Ultra-Small, Single/Dual/Quad Single-Supply Comparators VDD VDD VDD VDD VIN IN+ OUT VIN IN+ OUT 10k IN- IN- MAX9031 0.1F MAX9031 VSS VSS Figure 1. Additional Hysteresis Figure 2. Time Averaging of the Input Signal for Data Recovery 1) Find the trip points of the comparator using these formulas: Board Layout and Bypassing VTH = VREF + [((VDD - VREF)R2) / (R1 + R2) VTL = VREF(1 - (R2 / (R1 + R2))] where VTH is the threshold voltage at which the comparator switches its output from high to low as VIN rises above the trip point. VTL is the threshold voltage at which the comparator switches its output from low to high as VIN drops below the trip point. 2) The hysteresis band will be: VHYS = VTH - VTL = VDD(R2 / (R1 + R2)) 3) In this example, let VDD = +5V and VREF = +2.5V. VTH = 2.5V + 2.5(R2 / (R1 + R2))V and VTL = 2.5[1 - (R2 / (R1 + R2))] 4) Select R2. In this example, we will choose 1k. Use 100nF bypass as a starting point. Minimize signal trace lengths to reduce stray capacitance. Minimize the capacitive coupling between IN- and OUT. For slowmoving input signals (rise-time > 1ms), use a 1nF capacitor between IN+ and IN-. Biasing for Data Recovery Digital data is often embedded into a bandwidth and amplitude-limited analog path. Recovering the data can be difficult. Figure 2 compares the input signal to a timeaveraged version of itself. This self-biases the threshold to the average input voltage for optimal noise margin. Even severe phase distortion is eliminated from the digital output signal. Be sure to choose R1 and C1 so that: CAR >> 1 / (2R1C1) where CAR is the fundamental carrier frequency of the digital data stream. 5) Select VHYS. In this example, we will choose 50mV. 6) Solve for R1. VHYS = VDD(R2 / (R1 + R2)) 0.050V = 5(1000/(R1 + 1000))V where R1 100k, VTH = 2.525V, and VTL = 2.475V. The above-described design procedure assumes rail-torail output swing. If the output is significantly loaded, the results should be corrected. www.maximintegrated.com Maxim Integrated 7 MAX9030/MAX9031/ MAX9032/MAX9034 Low-Cost, Ultra-Small, Single/Dual/Quad Single-Supply Comparators Typical Application Circuit VDD 0.1F VIN R1 VDD IN+ VIN OUT VREF IN- R2 RL MAX9031 Package Information For the latest package outline information and land patterns (footprints), go to www.maximintegrated.com/packages.
